Title: Solid phase growth method of polycrystalline semiconductor thin film
Inventor: TOMITA TAKASHI
IPC: H01L21/324
Filed: 1985-09-13
Abstract: PURPOSE:To make large crystal grains growth at desired positions, by forming a nonuniform density distribution of impurity atoms in a polycrystalline semiconductor thin film by applying ion beam irradiation of impurity atom, and performing solid phase growth by thermal treatment. CONSTITUTION:A polycrystalline Si film 2 is irradiated intermittently with an equal interval by an iron beam 4 having an intensity distribution approximate to the Gaussian distribution. In this polycrystalline Si film 2, a periodical density distribution of impurity atom in which the Ganssian distribution is periodically repeated is formed, and a solid phase growth is performed by annealing. Thereby, the growth of crystal grains can be progressed with priority from the part of low impurity atom density, and extended to the outer region of high impurity atom density with high growth speed. Thus, large crystal grains with a diameter of about 10-100mum can be grown in the part of low impurity atom density, with excellent reproducibility.
